1991 Topps Desert Shield Baseball cards

I have two George Brett, two Cal Ripken, two Jose Canseco, Bo Jackson, Roger Clemens, Kirby Puckett, Ken Griffery Jr, Frank Robinson, Ricky Henderson, entire White Sox, Cubs, and Reds team of the 1991 Topps Desert Shield baseball cards, they are not professionally graded but I do believe there are in perfect condition, I know it's a bias opinion. I just can't really find any info about these item and I would like to know more about them. I would appreciate any help anyone can give me.
